Premaxillary Osteotomy and Guided Tissue Regeneration in Secondary Bone Grafting in Children with Bilateral Cleft Lip and Palate

Does the adjunctive use of autologous platelet concentrate during secondary alveolar bone grafting reduce the risk of wound dehiscence? A systematic review and meta-analysis

Wound dehiscence is a common complication after secondary alveolar bone grafting (SABG), leading to unfavourable surgical outcomes. Studies have shown that autologous platelet concentrates (APC) may enhance wound healing and improve outcomes. Therefore, this review aimed to evaluate in patients with alveolar clefts, whether using APC and iliac crest bone graft can mitigate the likelihood of wound dehiscence formation compared with those who underwent iliac bone grafting only following SABG. A comprehensive literature search was conducted using various electronic databases, including PubMed, Embase, Scopus, Web of Science, EBSCOhost, Ovid MEDLINE, LILACS, Cochrane Library, and grey literature, to include studies until July 31, 2023, without any restriction to language and time of publication. Only randomized (RCT) and controlled (CCT) clinical trials were included. Two independent reviewers screened the studies based on the predefined criteria, after which a qualitative and quantitative analysis was conducted. The search yielded 821 studies, of which seven were deemed eligible for systematic review. The risk of bias assessment done using "The Cochrane collaboration tool for risk of bias assessment" for six RCTs and the "Risk of Bias in Non-randomized Studies - of Interventions" for one CCT revealed a moderate to high risk of bias. The meta-analysis of five studies showed that the overall risk of developing wound dehiscence was lower in the APC group (RR = 0.33; 95% CI: 0.16, 0.71; p = 0.005; χ2 = 0.82; I2 = 0%). Subgroup analyses based on study design further supported these findings. Although the adjuvant use of APC for alveolar cleft reconstruction reduces the risk of wound dehiscence, more studies with increased scientific rigour and fewer confounding variables are warranted.

Primary vomerine osteotomy with gingivoperiosteoplasty for bilateral cleft lip and palate patients with protrusion and/or torsion of the premaxilla

In patients with bilateral cleft lip and palate (BCLP) with protrusion and/or torsion of the premaxilla, achieving a favorable outcome with adequate facial and maxillary development remains challenging. In the present study, we report a retrospective cohort of patients with complete BCLP who were treated between 2017 and 2020 at a single center in Japan. We investigated the effects and complications of primary vomerine osteotomy (PVO) with gingivoperiosteoplasty (GPP) following pre-surgical orthodontics (PSO) for premaxillary protrusion and/or torsion. For patients with residual premaxillary protrusion and/or torsion after PSO, PVO, and GPP were performed. The distances and angles of the premaxilla were measured on dental casts before PSO, on the day of PVO, after PVO, and on the day of palatoplasty after cheiloplasty. We further assessed postoperative complications. From a total of 36 patients with complete BCLP after PSO, seven patients underwent PVO with GPP. Proper positioning of the premaxilla was achieved in all seven patients. The distance between the anterior edge of the premaxilla and the anterior edge of the lateral segment and the length of the premaxillary-lateral segment on both sides continued to decrease over time. Loosening of GPP sutures occurred in two cases, although no major complications such as necrosis of the premaxilla or fistula formation occurred. Vomerine osteotomy with GPP before primary cheiloplasty is a potential treatment option in BCLP when the premaxilla still protrudes despite PSO or because PSO cannot be applied.

What is the Effectiveness of Premaxilla Surgical Repositioning and its Stabilization Methods in Mixed Dentition Patients With Bilateral Cleft Lip and Palate?

OBJECTIVE

Verify the effectiveness of surgical repositioning of the premaxilla and its stabilization methods in patients with bilateral cleft lip and palate during mixed dentition.

DESIGN

Systematic review.

MATERIAL AND METHODS

The search was conducted in 7 databases (eg, Medline via PubMed; Scopus; Central Cochrane; LILACS; Embase, Web of Science; and Sigle via OpenGrey until August 2021), using the descriptors "premaxilla", "cleft Palate", and "bone transplantation".

INCLUSION CRITERIA

Clinical trials and observational studies that have patients with bilateral cleft who had a need for superior/posterior repositioning of the premaxilla on mixed dentition; Studies in any language was evaluted whitout time restriction of publication.

RESULTS

From 5572 records, 6 studies were included in the review with a total sample of 212 patients. Regarding the type of stabilization used in the premaxilla, the hybrid method (rigid and complementary semi-rigid stabilization) predominated, being observed in 184 patients (86.8%). A total of 17 failures were identified related to the surgical repositioning of the premaxilla, corresponding to 8% of the total number of surgeries. A meta-analysis of prevalence was performed, only with the retrospective studies. It was observed that the effectiveness rate of premaxilla repositioning was 92%, with a CI between 0.04 and 0.13, with all included studies showing a similar failure rate (0.08-0.09). The included studies also showed great homogeneity in this analysis (I2 = 0%; P = .75).

CONCLUSION

Although there are several alternatives and techniques for repositioning and stabilizing the premaxilla, the statistical result did not differ between the different techniques.

Influence of a resorbable collagen membrane for alveolar bone graft on clinical outcomes and ridge volume stability in cleft alveolus

This study compared the clinical outcomes, graft quality, and graft quantity after alveolar bone grafting with and without a resorbable collagen membrane. Twenty unilateral cleft patients undergoing defect repair with cancellous iliac bone were assigned to either the collagen membrane group (Mb group) or standard group without a membrane (St group). Postoperative pain and swelling, bone density, and bone volume and quality were assessed. The Mb group showed significantly lower postoperative pain than the St group (P < 0.001) and significantly less swelling (P < 0.01) on day 3 postoperative. The reduction in bone density was significantly greater in the St group than in the Mb group at 1 and 3 months postoperative (P ≤ 0.001), but not at 6 months. The reduction in bone volume in the St group was significantly greater than that in the Mb group at 3 months (29.11 ± 6.26% vs 17.67 ± 11.89%, P = 0.016) and 6 months postoperative (40.95 ± 6.81% vs 25.67 ± 11.51%, P = 0.002). Nine cases in the Mb group versus six in the St group showed good bone quality. In conclusion, the collagen membrane facilitated predictable clinical outcomes in bone maturation, bone volume preservation, and bone bridging in the alveolar bone graft.

Lag screw fixation of the premaxilla during bilateral cleft lip repair

In synchronous primary premaxillary setback and cleft lip repair for bilateral cases with severely protruding premaxilla, stabilization of the premaxilla is mostly achieved by gingivoperiosteoplasty. This kind of repair carries risk of impairment of blood supply to the premaxilla and/or prolabium, and at the same time it cannot ensure adequate stabilization of the premaxilla postoperatively. To overcome these problems, we have developed a unique technique of fixation of the premaxilla. In this paper, we discussing this technique, its advantages, and potential complications associated with it. From 2016, 10 patients aged 4-10 months, with bilateral cleft lip and palate with premaxillary protrusion (≥10 mm) underwent premaxillary setback and cheilorhinoplasty in the same stage. Instead of gingivoperiosteoplasty, a 'lag screw' fixation technique was used to stabilize the premaxilla. The follow-up period ranged between 5 and 32 months. In all the cases, we achieved adequate stabilization of the premaxilla. None of the patients had any issue related to the vascularity of the premaxilla or prolabium. There was no impairment in the eruption process of deciduous teeth in the premaxillary segment. Overall aesthetic outcomes of the lip and nose were acceptable. This technique of premaxillary fixation with lag screw gives us the liberty to perform primary cheilorhinoplasty along with premaxillary setback in the same stage, without risking the vascularity of premaxilla and prolabium. It ensures adequate stabilization of the premaxilla, but evaluation of regular growth of the midface and, if needed, corrective orthodontic and surgical treatment in the follow-up periods are advisable.

Evaluation of Congenital Maxillary Growth Using Computed Tomography in Patients With Bilateral Cleft Lip and Palate

OBJECTIVE

To analyze congenital lateral maxillary growth for patients with bilateral cleft lip and palate (BCLP).

DESIGN

A retrospective study.

SETTING

Kanagawa Children's Medical Center.

MATERIALS

Images from computed tomography (CT) of patients with BCLP and control patients that were previously used for treatment.

MAIN OUTCOME MEASURES

The following landmarks were used: A, the posterior most point of the piriform aperture; B, the superior most point of the acoustic meatus; C, the point at which line A-B intersects the line drawn perpendicular from line A-B to the maxillary tuberosity; and D, the apical most point of the nasal bone. The following distances were then measured using these landmarks: (1) A-B distance; (2) A-C distance; (3) A-C/A-B; (4) the angle between lines A-B and A-D (∠BAD); and (5) B-D distance.

RESULT

Mean A-B and A-C distances and A-C/A-B were significantly smaller in the BCLP group than in the control group (P < .01 each). Mean ∠BAD was significantly larger in the BCLP group than in the control group (P < .01). Mean B-D distance did not differ significantly between groups.

CONCLUSIONS

Our results indicated that the lateral maxillary segments of patients with BCLP were more posterior than those of the control group, and segment length was shorter compared to the control group on 3D-CT analysis. The lateral maxillary segments of patients with BCLP were basically suggested to originally be underdeveloped.

Orthodontic premaxillary setback versus premaxillary osteotomy with gingivoperiosteoplasty for Bilateral cleft lip and palate patients: 4-year observation outcomes

Patients with bilateral cleft lip and palate (BCLP) generally require several stages of treatment, and adequate maxillary development without orthognathic surgery is not easy to achieve. The purpose of this study was to determine short-term outcomes of orthodontic premaxillary setback (OPS) and premaxillary osteotomy (PO) for complete BCLP treatment.

PATIENTS AND METHODS

Twenty-six patients with BCLP were consecutively treated for 4 years by a single surgeon. All patients were categorized by three indications for the first operation: OPS1, cheiloplasty + gingivoperiosteoplasty (GPP) + palatoplasty; OPS2, cheiloplasty + GPP; and PO, cheiloplasty + GPP + PO. Cephalograms for maxillary growth and velopharyngeal function (VPF) were judged at 4 years old, before orthodontic treatment.

RESULTS

OPS1 was performed in 14 cases, OPS2 in 8 cases, and PO in 4 cases. As for cephalometric analysis at 4 years old, no significant differences between groups were seen in any cephalometric measurements. As for speech outcomes, assessment of VPF at 80.8±14.8 months was good in 17 cases, slightly impaired in 8 cases, and marginally impaired in 1 case, with no severely impaired cases.

DISCUSSION

No significant differences in maxillary growth or speech outcomes were seen between OPS1, OPS2, and PO groups at 4 years old, possibly because all groups showed the same position of the premaxilla after the first operation.

CONCLUSIONS

No significant differences in maxillary growth or speech outcomes were seen for 26 patients with BCLP between OPS1, OPS2, and PO groups at 4 years old. However, the long-term growth characteristics remain unclear.

Incidence of complications in secondary alveolar bone grafting of bilateral clefts with premaxillary osteotomy: a retrospective cohort study

OBJECTIVE

To evaluate factors affecting incidence of complications after secondary alveolar bone grafting with premaxillary osteotomy (SABG + PO) in children with complete bilateral cleft of lip and palate (BCLP).

MATERIALS AND METHODS

Data were collected from children with BCLP treated with SABG + PO from 2004 to 2014 at our institute. Preoperative parameters included age, donor site, race, gingival health, bone quality around cleft-related teeth, premaxilla position, graft timing, presence of canines in the cleft, and presence of deciduous teeth around the cleft area. Logistic regression and the chi-squared test were used to assess correlations and the incidence of complications.

RESULTS

In the 64 patients, a significant correlation was found between complication rate and timing of bone grafting with respect to early versus late SABG + PO (p = 0.041), age > 12 years (p = 0.011; odds ratio (OR) 5.9; 95% confidence interval (CI) 1.49-23.93), malposition of the premaxilla (p = 0.042; OR 3.3; 95% CI 1.04-10.13), and preoperative bone quality around cleft-related teeth (p = 0.005; OR 5.3; 95% CI 1.6-17.2).

CONCLUSIONS

The timing of SABG + PO is essential, as early SABG + PO is associated with fewer complications. A malpositioned premaxilla and poor bone quality around cleft-related teeth are associated with more complications. Therefore, preoperative orthodontic repositioning of the malpositioned premaxilla before SABG + PO should be considered.

CLINICAL RELEVANCE

Analysis of treatment protocols and complications for BCLP patients underscores that proper timing of SABG + PO and correct premaxilla repositioning help reduce complications.

Surgical Repositioning of the Premaxilla Using a Minimally Invasive Endonasal Approach

Objective:

The aim of this study was to evaluate a technique for the surgical repositioning of the premaxilla using a minimally invasive endonasal approach.

Design:

Retrospective review of clinical records.

Setting:

Tertiary care, University Hospital, pediatric maxillofacial surgery unit.

Patients:

Twenty-one patients (12 boys and 9 girls), ages ranging from 6 to 21 years, with BCLP+A and premaxillary malposition (PM).

Interventions:

Surgical repositioning of the premaxilla (SRP) using a minimally invasive endonasal approach, from November 2007 to November 2015.

Main outcome measures:

Achieving maxillary arch alignment and premaxillary stability was defined as treatment success. Intraoperative and postoperative complications were also recorded.

Results:

In all cases (100%), the treatment was successful either at first surgery or after reoperation. Two patients (9.5%) were reoperated-one due to premaxillary instability and one due to PM relapse. There were no perioperative complications.

Conclusions:

SRP using a minimally invasive endonasal approach is a safe and effective technique that levels and aligns the maxillary arch in preparation for SABG, which minimizes the risk of wound infection and premaxillary vascular compromise. The endonasal approach improves tissue quality of the mucoperiosteal flaps when performing the SABG procedure. Further prospective studies are needed to elucidate the best protocols and techniques for the management of PM in patients with BCLP+ A.

Synchronous Premaxillary Osteotomy with Primary Cheiloplasty for BCLP Patients with Protrusion of the Premaxillae

Supplemental Digital Content is available in the text.

Background:

In bilateral cleft lip and palate (BCLP) patients with protrusion and/or torsion of the premaxillae, it is difficult to achieve a good outcome. We have developed a series of procedures of premaxillary osteotomy with primary cheiloplasty for BCLP patients who did not respond well to presurgical orthodontics (PSO).

Methods:

A total of 27 BCLP patients with protrusion and/or torsion of the premaxillae underwent PSO. For 3 BCLP patients in whom the protruded premaxillae could not be returned to a good position, a primary premaxillary osteotomy and gingivoperiosteoplasty (GPP) with cheiloplasty were performed simultaneously. Subsequently, Furlow palatoplasty was performed by one and a half years of age. Maxillary growth was evaluated by dental occlusion at 4 years of age.

Results:

A premaxillary osteotomy and GPP with cheiloplasty were performed at 6 months. The patients’ facial structures improved, their premaxillae were positioned more superiorly, and normal inclination of the incisors was achieved. They had edge-to-edge occlusions or cross bites at 4 years of age.

Conclusions:

As advantages, the patients’ facial structures improved, and the alveolar bones were formed by GPP. As a disadvantage, premaxillary necrosis might occur because of poor blood circulation. It is important to secure the following 2 blood supplies: from the periosteum and soft-tissue of the anterior premaxillae and from the periosteum and mucosa of the nasal septum. Synchronous premaxillary osteotomy and GPP with primary cheiloplasty are appropriate when the premaxillae cannot be properly repositioned by PSO or PSO cannot be done.

[Timing of alveolar bone graft and sequences of canine eruption in cases of cleft lip and palate: a systematic review]

INTRODUCTION

The alveolar bone graft (ABG) is an important phase in the surgical treatment of cleft lip and palate (CLP). The purpose of alveolar bone grafting is to eliminate oronasal fistulas, restore the continuity of the maxilla and provide optimal periodontal support for spontaneous eruption of permanent canines adjacent to the cleft. The purpose of this systematic review was to determine the ideal timing of the ABG that would achieve these goals.

MATERIAL AND METHODS

Databases consulted were MEDLINE, Embase et EBSCOhost, using keywords present in the MeSH: [cleft lip and palate] and [alveolar bone graft] and [tooth eruption]. Selection criteria included retrospective studies, prospective studies and meta-analyzes dating from January 2005, with available full text.

RESULTS

Among 105 references, 9 articles met our selection criteria. ABG carried out before or just after the eruption of permanent canines adjacent to the cleft, between 8 and 12 years old, has the best success rate of the transplant (71% to 89%) and the lowest risk of canine inclusion (5% to 19%).

CONCLUSION

According to literature data, the optimal timing of ABG that provide best results is located between 8 and 12 years, before or just after the eruption of permanent canines adjacent to the cleft. However, this timing could be modified by the multidisciplinary team according priorities, particularly aesthetic, defined for each child.

Outcomes of 44 Consecutive Complete Bilateral Cleft Lip and Palate Patients Treated with Secondary Alveolar Bone Grafting and Premaxillary Osteotomy

Objective

To report the surgical outcomes of secondary alveolar bone grafting with premaxillary osteotomy in a single surgeon cohort of complete bilateral cleft lip and palate patients.

Design

Retrospective review of 44 consecutive patients using hospital notes and radiographs.

Setting

Single specialist cleft lip and palate center, UK.

Patients

Consecutive patients with complete bilateral cleft lip and palate who were being treated with secondary alveolar bone grafting incorporating premaxillary osteotomy.

Outcome Measures

Assessment of success of bone graft by Kindelan score; canine eruption; closure of fistulae and assessment of morbidity.

Results

Between January 6, 2000, and August 8, 2013, 44 patients with complete BCLP underwent secondary ABG with a premaxillary osteotomy as a one-stage procedure. The mean follow-up was 7.3 years (range 1.4 to 14.6). Eighty-five percent of ABGs were successful (a Kindelan score of 1 or 2), and canine eruption was 89%. Failure of the ABG occurred in 7%. Fistulae recurrence rate was 11%, all of which were asymptomatic. No premaxillae were devitalized.

Conclusion

Incorporating a premaxillary osteotomy into the secondary ABG surgical protocol can be a safe technique that gives excellent surgical exposure for fistula repair.

Stabilization of premaxilla repositioned during secondary bone grafting in complete bilateral cleft lip and palate patients

Secondary bone grafting simultaneous to premaxillary repositioning is a well-recognized surgical procedure for the management of bilateral cleft lip and palate patients. Proper stabilization of the repositioned premaxilla is considered as a key factor for the success of secondary bone grafting because the mobility of the premaxillary segment jeopardizes graft integration. This case series reports a reliable method of premaxillary stabilization that incorporated the intrasurgical application of resin bone cement to cover and reinforce the arch bars or orthodontic brackets applied on the maxillary teeth. Occlusal loads were reduced by application of posterior bite blocks on the mandibular teeth. The stabilization method was performed on 7 patients (5 women and 2 men) with a mean age of 12.4 years. During postsurgery follow-ups, the repositioned premaxillary segments did not show mobility in any of the patients. The palatal fistulae were completely closed. Panoramic radiographies taken 2 months after surgery demonstrated acceptable graft integration. The patients have now been followed up to 5 years. No evidence of relapse has been observed. This technique seemed to be undemanding, included minimal laboratory procedure, and maintained the labial mucosa overlying the repositioned segment intact.

Management of the premaxilla in the treatment of bilateral cleft of lip and palate: what can the literature tell us?

Objective

In the treatment of bilateral cleft lip and palate (BCLP) patients, there is discussion about the management of the position of the premaxilla. This literature analysis summarises the literature on managing this condition.

Materials and methods

A PubMed, Embase and Cochrane Library search was conducted resulting in 4465 articles which were screened on title and abstract.

Results

Seventy-one articles were available in full text, 16 of which were included in this literature analysis. We searched on keywords timing and technique, complications, growth of the maxilla and results after bone grafting the alveolar process. This literature analysis has shown that there are various ways to correct the position of the premaxilla. These can be divided into primary, early, late secondary and tertiary intervention before the age of 8 years, between the ages of 8 and 12 years and older than 12 years. Correction is done with surgery, orthodontics or a combination, with or without bone grafting.

Conclusions

An osteotomy of the premaxilla in combination with secondary alveolar bone grafting appears to be the most successful technique. Combining early secondary alveolar bone grafting with osteotomy creates more room to ensure a watertight closure of the nasal mucosa resulting in fewer postoperative complications. Before surgery, the orthodontist should try to optimise the position of the premaxilla for its surgical correction prior to bone grafting.

Clinical relevance

The treatment of BCLP patients is still based on experience and expert opinions. This literature analysis tries to give a summery on how to handle the protruded and displaced premaxilla.

Premaxillary osteotomy fixation in bilateral cleft lip/palate: Introducing a new technique

OBJECTIVES

In bilateral cleft lip/palate patients, sometimes the premaxilla is severely protruded and twisted. In such situations premaxillary osteotomy is beneficial. In this article a new technique for fixation of premaxilla after osteotomy is presented.

METHODS

The lip-split approach and premaxillary osteotomy and ostectomy from bony nasal septum were carried out. Fixation of osteotomized premaxilla was achieved with low profile miniplate or microplate. Bone grafting of that side was performed during the same session.

RESULTS

This procedure was performed in three patients, with good labial repair after the lip split. The bone graft was successful in all the three cases and there were no complication for premaxillary osteotomy in this series.

CONCLUSION

In protruding premaxilla, osteotomy and fixation of premaxilla with miniplate to the vomer bone during alveolar bone grafting through a lip-split approach yielded satisfactory results in patients requiring secondary functional cheilorhinoplasty.

Early Orthopedic Retraction of the Premaxilla in Bilateral Complete Cleft Lip and Palate: An Innovative Approach to a Difficult Problem

Bilateral cleft lip and palate occurs in 9.2% of cleft patients. Many approaches have been adopted to manage the protrusive premaxillary segment in patients with bilateral cleft lip and palate. Some advocate the use of intraoral appliances, occasionally combined with invasive surgery, which often requires revision at a later date. The authors describe the case of a 3-year-old child born with bilateral cleft lip and palate presenting with a protuberant premaxilla and an overjet greater than 25 mm. Prompt intervention was warranted in this case due to the potential for traumatic compromise to the dentition of the premaxillary segment and a distinct lack of social integration reported by the parents. The patient was managed with a novel, innovative approach using orthodontic traction and minimally invasive surgery. The literature has been reviewed and the patient's subsequent physiological and psychosocial development has been monitored. He has since undergone successful alveolar bone grafting.

Simultaneous Premaxillary Repositioning and Cheiloplasty in Adult Patients with Unrepaired Bilateral Cleft Lip and Palate

Primary cheiloplasty in adult patients with unrepaired complete bilateral cleft lip and palate is quite challenging due to severe premaxillary anterior projection. To get the best repair results, the author carried out repositioning of the premaxilla and repair of the lip deformity in a single stage. Positive results for the primary lip repair and appropriate repositioning of the premaxilla were achieved. No avascular necrosis of the premaxilla was observed. Repositioning of the premaxilla and repair of the lip deformity in a single operation appears to be a reliable method for treating adult patients with previously unrepaired or poorly repaired bilateral cleft lip and palate.

Social integration and inclusion after pre-maxilla surgical repositioning in patients with bilateral cleft palate and lip

Bilateral alveolar process fissure causes important functional and aesthetical limitations and thus difficulties in terms of social and family integration and interaction for these patients.

AIM

(A) to assess motivations and expectations Treatment-wise and (B) to assess social inclusion and integration brought about by the surgery.

MATERIALS AND METHODS

retrospective observational study involving 50 participants recruited among the patients submitted to the pre-maxilla repositioning procedure from January of 2003 to July of 2005 at the Centro de Atendimento Integral ao Fissurado Lábio-Palatal in Curitiba (CAIF), Paraná, and an assessment questionnaire was used.

RESULTS

as far as the care protocol is concerned, results show a 90% success rate of surgeries. As to surgical and personal satisfaction rates are concerned, 76% sought treatment for personal satisfaction reasons and 86% reported having had more self-confidence after the surgery.

CONCLUSIONS

Most of the patients submitted to the maxilla repositioning saw surgery as a continuation of the care previously given, with the expectation of better looks and self-confidence and, 96% of them were pleased with the results attained, which facilitated their social inclusion and re-integration.
